Key facts

Recorded sex or gender
Documentation of a specific instance of sex and/or gender information. This concept does not represent an administrative sex/gender. Rather, the value of an administrative sex/gender (e.g. "F" or "Female") would be stored or "tagged" as a kind of recorded sex or gender. The values include, but are not limited to, F (female), M (male), X (non-binary, intersex, etc.), and < (value not recorded or cannot be ascertained for any reason). These values are based on the set in Doc 9303Machine Readable Travel Documents, Seventh Edition (2015), Part 7: Machine Readable Visas published by the International Civil Aviation Organization (ICAO). This term was created based on the Recorded Sex or Gender concept proposed by the HL7 Gender Harmony project within the Vocabulary Work Group.
